COIN-CONTROLLED LOCK.

Specification of Letters Patent.

Application filed November 14, 1907.

To all whom it may concern:

Be it known that I, HENRY B. MEADE, a

citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a' new and useful Im provement in Coin-Controlled Locks, of

which the following is a specification, the

principle of the'invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

lHy. invention relates to looks, and particularly to 1ocks, the operation of which is designed to be controlled. by a coin-actuated device or similar meansa lock of this type that will be particularly adapted for use in connection with lockers and the like where it is desirable'that exclusive use of a locker or compartment may be had by the payment of a coin;without possibility of such use being extended to others than those thus paying and without possibility of unauthorized tampering withthe locker or compartment. In other Words and more particularly, my improved lock is designed to normally' have the key held therein and the door locked, in which'con- .dition the coin will render the lock operable by the key, permit the subsequent Witlr drawal of the key, its insertion and a second operation of the lock, and then again retain such key against removal. \Vith a View to providing alocker of the above character that will be sim le in construction and operation and not liable to get out of order, said invention, then, consists of the means hereinafter fully described and particularly pointed'out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the prlnciple of the invention may be used.

In said annexed drawing: Figure 1 1s a side elevation of my improved lock mechanism shown as detached from the door or other part to which it may be aflixed in the usual fashion of mounting locks, the several parts in such figure appearing in .the. initial position above referred to wherein the key is held both against operating the lock and against removal; Fig. 2 is a similar View of such lock mechanlsm, the parts being therein shown as positioned at the con- Patented July 20, 1909.

Serial No. 402,052.

clusionof the first operation of the lock permitted by the insertion of a coin; Fig. 3 is a detail showing the coin actuating device Fig. 4 is a side elevation of one approved type of operating key such-as may housed in conjunction with the mechanism shown in Figs. 1 and 2; and Fig. 5 is a similar side elevation of the master key for said lock.

Having reference then to the several figurcs just described, A will be seen to designate the back of the case to which the several parts of the lock are attached and by which,

along with the front portion of suchcase, not shown, they are inclosed and protected 1 against the ingress of dirt or like material The object of the invention .is to rovide that might interfere with the working of such parts. Such case it will be understood may be inserted in a suitable mortise of the door or door jalnb, or may be secured bodily against the inner face of the same, as de? sired, depending upon the particular use to vwhich the lock is being put.

parts of the look, a rcci-procablebolt B conmember proper, and is Of the several stitutes the lockin normally retainedin its projecting or operating position 'by aspring b. Retraction' of the bolt is had by a key B of familiar construction, that, when properly inserted in the casing, Fig. 1, is adapted to engage a notch b on the under side of the bolt and socoin-actuating device D. The latter consists simply of a plate or arm d plvoted at w'vhich. extends intoengagement with the one side of a coin chute (l' and adapted to be actuated outwardly by the passage of a coin through the latter.: A spring d engaging an amid borne on the same shaft whereon such plate d is mounted, is adapted'to re siliently secure such plate either in its inwardly projecting, or set, position, or in the position in which it is placed by the passage of a coin as aforesaid. Such plate is provided with two arms 01* (i projecting out- Wardly from the chute, the upper (Z of which engages with the weighted end 0 of dog O and is effective, upon, the movement of the plate occasioned by the coin, to movesaid dog out of engagement with the key.

The function of the other arm at will be adverted to presently. Key B is not only held by dog G so-as to lie-unable to actuate the bolt, but also against removal from the lock by reciprocable keeper E that prevents rotation of the key to turn into register with the key-hole, so that it is confined by the front,

late of the case. Reciprocation of keeper to thus project the same and alternately withdraw 1t, leaving the key free to be re.-

moved, is had by means of a ratchet wheel Eprovided with a cam slot 6 on its one face in the form'of a star. The rear end of the keeper being formed with a pin 6 registering in such slot, it will be evident that upon successive partial rotations of the wheel the desired movement of the keeper will be secured. Such rotation of the wheel and operation of the keeper is effected jointly with successive retraction's of the bolt by means of a pawl e borne by the latter being pivotally mounted on its side.v Such pawl is normally held out of engagement with the ratchet wheel E by a spring 6 that bears against its under side, but is adapted,.upon engagement of the key B jointly with a downwardly projecting portion 6' thereof and with bolt B, to be depressed and engage the wheel simultaneously with the retraction of the bolt. By reason of this arrangement it will be obvious that actuation of the bolt from without, as might be attempted when the door has once been opened in order to.

disarrange the parts, is wholly impossible. This same mechanism, whereby kee or E is controlled, is also utilized to re-set t 1e coincontrolled device D and thereby to restore the weighted dog 0 to its normal efiective osition. To this end a lever E is provided,

ulcrumed at e, one arm 6 of which is connected' with thekeeper E whereby said lever is rocked simultaneously with the movement of the keeper effected by rotation of the ratchet wheel. The other arm 6 of the lever E projects into the path of the lower of the twoarms d whercwith plate (Z is provided. This arm a is constructed of sprin' metal so as to be capable of a slight latera movement and its outer'end is formed with a cam face 6 whereby upon upward movement of the arm such end will ride over the arm d From the foregoing the'operation of the mechanism as a whole should be fairly obvious. As has already been indicated the normal state of mechanism is that in which the key is locked both against withdrawal andsoas to be incapable of retracting the bolt. Assuming the lock to be attached to a door, it will accordingly be impossible to open, the latter. The insertion of the coin into the chute and its passage therethrough,

that he has carried may be readily inserted and the door opened s1nce both the keeper and the, dog' are inactive. Such second retraction of the bolt under action of the key, however, restores both the keeper and the dog a ain to their efi'ective positions and thus t e key cannot now be removed, nor, of course, can the lock be operated a second time without the deposit of another coin.

To permit actuation of the lock by authorized parties without deposit of a coin, or in case for'any reason the' mechanism of the lock should get out of order, I provide a master key F, Fig. 5, and mechanism operable thereby, Figs. 1 and 2, adapted to retract bolt B wholly independently of the coin-controlleddevice above described. Such mechanism consists simply of a small pinion .f, mounted on the inner face of the case A and meshing with a rack if on the upper side of bolt B. The end o key F is longitudinally grooved or flutedto form a pinion P that when properly inserted is adapted to rotate inion f and thus retract bolt B wholly in ependently of the mechanism before described.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the meansstated by any of the fol lowing claims or the equivalent of such stated means be employed.

. I therefore particularly point out and distinctly claim as my -invention 1.
